The Gold Standard in High-Performance Insulation
East Coast Foam and Coating Supply proudly offers Closed Cell Spray Foam — a professional-grade insulation material known for its unmatched strength, moisture resistance, and thermal performance. Ideal for both commercial and residential projects, this high-density foam forms a rigid, durable barrier that insulates, air-seals, and adds structural integrity to any building.
Whether you’re working on a new build, retrofit, or metal structure, closed cell spray foam delivers maximum efficiency and long-term value.
What Is Closed Cell Spray Foam?
Closed cell spray foam is a dense polyurethane insulation in which the individual cells are completely encapsulated, preventing air and moisture infiltration. Unlike open cell foam, it is hard to the touch and creates a vapor-resistant shell. This results in a superior R-value, greater durability, and a built-in moisture barrier in a single application.
Key Features & Benefits
- High R-Value Performance
Achieves an R-Value of ~6.5–7.0 per inch, making it one of the most thermally efficient insulations available. - Moisture & Vapor Barrier
Closed cell structure repels water and blocks moisture — no additional vapor barrier required in many applications. - Structural Strength
Adds rigidity to walls, roofs, and panels, helping to increase the structural integrity of the building envelope. - Energy Savings
Reduces heating and cooling costs by up to 50% when professionally installed with proper sealing techniques. - Space-Saving
Higher R-value per inch means less thickness is needed, making it ideal for tight spaces or code-restricted cavities. - Excellent Adhesion
Bonds to virtually any clean, dry surface — wood, metal, concrete, and more.
Common Applications
Exterior walls (residential & commercial)
Metal buildings and warehouses
Below-grade foundations
Roof decks and attics
Crawlspaces and basements
Cold storage & refrigerated units

Fire Safety & Code Compliance
All of our closed cell foam products meet or exceed IBC and IRC building code requirements. Most formulations include fire-retardant additives and are certified for use with thermal or ignition barriers as needed.
Low-VOC and non-toxic when cured, our foam is manufactured with environmentally responsible blowing agents.
